Few countries in the world face as immediate a threat from climate change as the Republic of Maldives, a low-lying group of atolls in the Indian Ocean whose coastline is eroding and whose water supplies are now being infiltrated by saltwater from the sea.

Guerrero's coastline is so long that it is divided into two regions, the Costa Chica, which starts just south of Acapulco and continues east to the Oaxacan coast, and the Costa Grande, which is all of the coastline northwest of Acapulco.

This seems like a good time of year to talk about the culinary specialties of Guerrero, the Mexican state whose coastline is home to some of the country's most popular winter resorts, including Acapulco and Zihuatenejo.
